Notes

Fly-back Fly-back or "Retour en vol" refers to the instantaneous fly-back feature of a chronograph?s sweep second hand. On a regular chronograph, this hand can only be reset to zero, after being stopped by a push of the stop button, but a fly-back mechanism allows resetting the hand to zero, while still in motion by a single push on the lower chronograph or reset button. Therefore, the process of timing an event can be immediately resumed. This feature proved especially useful in early aviation, allowing a pilot saving time and devoting full attention to flight maneuvers.
